Abstract
Natural gas is stored in a closed vessel under a pressure of about 1400 to 4500 kPa using a carbon molecular sieve adsorbent. The deliverable volume of natural gas from a vessel packed with carbon molecular sieve particles is increased by raising the density of the polymer precursor of the carbon molecular sieve through adjustment of the conditions for suspension polymerization of vinylidene chloride.
